<p>Seems probable. To be clear, the situation was something like:</p>
<ul>
<li>we optimize libstd more (perhaps do more inlining)</li>
<li>this in turn increases size of all binaries</li>

<p><span class="user-mention" data-user-id="116009">@nikomatsakis</span> I only just now caught up to this mention. (Also, I'm a little behind dealing with the target tier RFC, but I still intend to go back and incorporate feedback and post a new version.)</p>
